A pulse is still considered a small front and this time of yr any kind of front being big or little will effect the situation..First of all what i would do my freind is with the water temp being what you said i would not key on flooded shore brush or bushes,,unless it was a single tree or bush that was 20 or 30 feet off the original shore being before flooded..Just think the water is warming up pretty soon these bass are going to try and spawn and they are going to be stagin on secondary points and flats being the situation with them pulling the water the fish will be suspended off the shore but not real deep,,some will be around cover but most your big fish will be above the cover being afraid the water will catch them shallow.. KEY ON A FLUKE FOR THEM BEING SUSPENDED NEAR SECONDARY POINTS CLOSE TO A BIG COVE,,.IF THAT DONT GET IT THROW A 7 TO 9 FT DIVIN CRANKBAIT,,IF THAT DONT DO IT GO TO A SHAKY HEAD AND FISH IT SLOW WITH A BULKY BIG WORM OF SOME KIND..I DONE THE VERY SAME THING SUNDAY ON GREEN RIVER LAKE WITH THE WATER IN THE SAME SHAPE THAT BARKLEY IS IN AND WE SLAYED THEM ON A FLUKE AND CRANKBAIT ON SECONDARY POINTS ONLY AT BIG COVES..I HOPE THIS HELPED YOU A LITTLE.LET ME KNOW.. THANK YOU.
